Spiral Cooler Freezer For Bakery Products
After baking or forming, bakery products require controlled thermal treatment such as cooling, proofing, drying, or freezing to stabilize structure and prepare for packaging. Spiral conveyor systems enable continuous processing with high space efficiency and uniform product handling.
Process bakery products with vertical spiral conveyors and controlled airflow
The spiral conveyor systems from SARP are designed for continuous processing of bread, pastries, pizzas, and baked goods, supporting multiple process steps including cooling, freezing, proofing, drying, pasteurization, and sterilization.
Products are transported on specialized conveyor belts arranged in vertical spiral configurations, allowing long residence times within a compact footprint. The spiral is driven by a central tower, leaving space within the structure for integrated air treatment systems, enabling efficient thermal exchange.
The system is designed to achieve high air-to-product contact (close to 100%), ensuring uniform temperature distribution during cooling or freezing. Depending on the application, the system can operate:
- In open-air environments for ambient cooling or drying
- Inside insulated chambers for controlled freezing, proofing, or pasteurization
The conveyors are engineered to handle both packed and unpacked products, with belt designs that prevent sticking, deformation, or surface marking. The system also minimizes lubrication needs, supporting hygienic operation and reducing contamination risks.
To improve line efficiency, the system can function as a buffer or accumulation unit, maintaining product flow when upstream or downstream equipment temporarily stops.
Typical applications include:
- Bread loaves and rolls
- Croissants and pastries
- Pizzas and dough-based products
- Cakes, cookies, and desserts
Benefits
- — Vertical spiral design maximizes capacity in limited floor space
- — High airflow efficiency for uniform cooling and freezing
- — Supports multiple processes: cooling, proofing, drying, freezing
- — Can operate in open-air or insulated environments
- — Acts as buffer to stabilize continuous production lines
